Efficacy and Safety of 20% and 100% Autologous Serum Eye Drops in Patients With Severe Dry Eye Disease: a Prospective, Blinded, Randomized, Crossover Study
In Brief
A clinical study evaluating Preservative-free artificial tears, Autologous serum eyedrops 20%, and 1 other intervention for Dry Eye Disease. Completed, enrolled 46 participants across 1 site.
Detailed Summary
A prospective, single-blinded, randomized, controlled crossover trial was conducted in patients with severe dry eye syndrome. Topical treatment with autologous serum eye drops (ASED) diluted at 20%, undiluted ASED and conventional preservative-free artificial tears (PFAT) were compared as a treatment for severe dry eye disease. The primary outcome measure was assessment of ocular symptoms using the Ocular Surface Disease Index (OSDI) questionnaire. Secondary outcomes were Schirmer 1 test, best-corrected visual acuity (BVCA), corneal fluorescein and conjunctival lissamine green staining using the Sjögren's International Collaborative Clinical Alliance Ocular Surface Staining (SICCA OSS) score, tear break up time (TBUT), conjunctival injection score (CIS) and Meibomian gland dysfunction (MGD) grading. Additionally, serum and tear cytokine analysis and microbiological cultures were performed.

Timeline
Interventions
Each patient received three 8-week treatments in a randomized sequence, being PFAT, AS 20% and AS 100%. After 8 weeks of treatment, the treatment effect was evaluated during a scheduled study visit. The patient was then instructed to start a new washout of 2 weeks to immediately follow with the next treatment.
